Is there a pin-compatible replacement for TPS62163DSGR?

Currently, no pin-compatible replacement has been identified. The target's WSON-8 package is not matched by common alternatives, which are typically in larger SOP-8 packages.

What risks should I check before replacing TPS62163DSGR?

Key risks are: 1) Package mismatch requiring a new PCB layout. 2) A much lower switching frequency, which will require a larger inductor. 3) A higher minimum input voltage, which may not work. 4) Different control topology affecting efficiency.

TPS62163DSGR Alternatives, Datasheet & Cross Reference | Texas Instruments

The TPS62163DSGR is a high-frequency, high-efficiency 1A synchronous buck converter in a compact WSON package. Finding a substitute requires careful review of package, switching frequency, and input voltage range.

AI replacement insight

Electrical riskhigh

Different frequency, topology, and input voltage requires recalculating all external components.

Package riskhigh

Target WSON-8 is not compatible with candidate SOP-8 packages, requiring a new PCB layout.

Firmware risklow

The component is a hardware-configured regulator with no firmware interaction.

Can it be replaced directly?

No direct or pin-compatible replacement is available among the candidates reviewed.

Best replacement path

Use a parametric search for synchronous buck converters with Vin(min) <= 3V, Fsw > 1MHz, and Iout >= 1A, then adapt the PCB layout.

Main risk

A complete circuit and layout redesign is required due to major differences in package, switching frequency, and input voltage.

Recommended alternatives

A high-voltage functional alternative, but requires a new layout and has a different switching frequency.
